I've noticed that my static IPv6 has gone down after my connection dropped and reconnected at 2am this morning. As of the time of this post, it still hasn't returned. Any problems with this? I use IPv6 for a number of services so its important (relative to the fact I'm on a home and not business connection).

Had a similar situation recently. 2degrees claimed it was all good on their end. I ended up disabling the setting "Use DHCPv6 Rapid Commit" in my Fritz box and that allowed IPv6 to connect. Re-enabling and it wont connect. I've left it off for now. Seems to work fine.
